A buffer is a mixture of molecules that acts to keep the pH of a solution close to neutral. Check your answer. Buffers are extremely important to living organisms because all biochemical processes proceed normally only when the pH remains close to 7. Check your answer. When studying biomolecules in a test tube, the biomolecules may behave in ways that are uncharacteristic of their natural behavior if they are in a solution with a pH that is significantly different from the pH of their natural environment.
Heinrich Himmler (1900-1945) was the Reich Leader (ReichsfÃ¼hrer) of the dreaded SS of the Nazi party from 1929 until 1945. Himmler presided over a vast ideological and bureaucratic empire that defined him for manyâboth inside and outside the Third Reichâas the second most powerful man in Germany during World War II.
It was Heinrich Himmler, the head of the S.S., who was in charge of the camp system, and its growth was due in part to his ambition to make the S.S. the most powerful force in Germany. Long before the Nazis took power, concentration camps had featured in their imagination. Wachsmann finds Hitler threatening to put Jews in camps as early as 1921. But there were no detailed plans for building such camps when Hitler was named Chancellor of Germany, in January, 1933.
